ASP shopping Cart

I need an ASP shopping cart. A simple one with the following features : register, login, products, search, featured products, discount products and some small minor additions etc. This project is for a school assignment therefore i would require you to add notes on the codes. Like what does this code do, where does it extract data from etc etc, i think you know what i mean. The admin feature need to be very simple also , design also need be very simple. Please post your bid.
